  • In order to determine the most effective ratio of black soybean powder as an ingredient in cake, black soybean power was added at ratio of 10, 20, 30, and 40% versus wheat flour set as 0(control). Black soybean powder consisted of moisture(8.44%), crude protein(31.34%), crude fat(6.64%), crude ash(3.88%) and carbohydrates(49.70%). The specific gravity, spreadability, and baking loss increased according to the amount of black soybean powder, although specific volume decreased. The chromaticity 'L' and 'b' values of sponge cake with black soybean powder showed an reducing trend while the 'a' value displayed an increasing trend with an increase in black soybean powder. The texture properties of sponge cake with added black soybean powder showed an increasing trend in hardness and stiffness when the cake contained more black soybean powder. The sensory test for sponge cake with added black soybean powder showed high preference for 20% added black soybean powder to sponge cake.

  • We investigated the physical and cooking properties of commercial noodles supplemented with functional ingredients. RVA (rapid visco analyzer), color, water activity, texture and cooking properties were tested. Noodles containing kudzu showed the highest initial gelatinization temperatures, whereas noodle containing kelp displayed the highest peak viscosity and set back. Holding strength and final viscosity were highest in noodles containing mugwort. The L value ($94.89{\pm}0.02$) of wheat flour noodle was the highest. Among functional noodles, L value ($88.65{\pm}0.01$) and a value ($7.42{\pm}0.02$) of cactus noodle were the highest, whereas b value of pumpkin noodle was $40.81{\pm}0.03$, which was higher value than in other noodles. Water activity of cactus noodle was highest (0.455), but the difference was not significant. Cooking properties (including weight, volume, and water absorption) and turbidity of pumpkin noodles showed the highest growth rate. In terms of texture, hardness was highest ($12836.8{\pm}7.1g/cm^2$) in green tea noodles, and cohesiveness and gumminess were highest in kelp and mugwort noodles. Considerig the quality characteristics of noodles supplemented with mulberry leaves, cactus, mugwort, green tea, pumpkin, kelp or kudzu, pumpkin noodles were most stable in terms of gelatinization and cooking properties.

  • This study investigated the quality of noodles containing different amounts of Capsosiphon fulvescens powder. Noodles were prepared with C. fulvescens powder at ratios of 0, 1, 2, 3 and 4% based on flour weight. Cooking quality, mechanical texture properties, and viscosity were measured, and a sensory evaluation was performed with the prepared noodles. Gelatinization points of the composite C. fulvescens powder-wheat flours increased. As measured via amylography, viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity values of samples decreased as C. fulvescens powder content increased. As increasing amounts of C. fulvescens powder were added, L, a and b values decreased, whereas color values, weight, and volume of cooked noodles increased, as did turbidity of the soup. In the texture meter test, hardness, cohesiveness, and springiness increased according to increasing concentrations of C. fulvescens powder. However, adhesiveness of noodles decreased by addition of C. fulvescens powder. Sensory evaluation showed that high quality cooked noodles could be produced by 3% inclusion of C. fulvescens powder.

  • Soy sauce, a basic ingredient in Asian cuisine, is made of fermented soybeans, salt, water, and barley or wheat flour. The sensory characteristics of soy sauce are not only determined through its main ingredients but also by various flavor compounds produced during the fermentation process. This study was conducted to identify the sensory attributes of five different commercial soy sauce samples that differ in Meju types (traditional Meju or modified Meju) and usage types. Thirty three sensory attributes, including appearance (1), odor (16), flavor (14), and mouthfeel (2) attributes, were generated and evaluated by eight trained panelists. The collected data were analyzed by analysis of variance and principal component analysis. There were significant differences in the intensities of all sensory attributes among the soy sauce samples. Soy sauce made with traditional Meju had high intensity of fermented fish, beany, musty odors and salt, Cheonggukjang, fermented fish flavors. Whereas two soy sauces made with modified Meju were strong in alcohol, sweet, Doenjang, roasted soybean flavors. Two soy sauces for soup made with modified Meju had medium levels of briny, sulfury, fermented odors and bitter, chemical flavors and biting mouthfeel characteristic.

  • Physicochemical properties and consumer perception of white pan bread as influenced by the addition of Ecklonia cava powder (ECP) were investigated. Freeze-dried Ecklonia cava were ground, sieved through a laboratory sieve and a fraction with particles less than $250{\mu}m$ was used. Amount of ECP added (0~3%) to the bread was found to affect the bread quality significantly (P<0.05). pH, bread height, and volume of the control was significantly higher than others (P<0.05) and decreased significantly (P<0.05) with the addition of ECP. Moisture content showed no significant differences (P>0.05). There were distinctive color changes with the addition of the powder: $L^*$- and $a^*$-values decreased but $b^*$-value increased significantly (P<0.05). The hardness of bread was found to increase but both cohesiveness and springiness showed a reverse trend with the addition of the powder. Consumer acceptance test indicated that ECP content 1% on wheat flour could be the recommended supplementation level for the consumers without sacrificing sensory quality.

  • In this study, the microwave free-space transmission technique was used to measure the dielectric property of powdered food at microwave frequencies. The sample holder was designed and fabricated to transmit the microwave signals ranging from 1 to 15GHz. From the microwave propagation theory the equation expressing the dielectric property of powdered food was derived and validated by standard dielectrics. The dielectric property of powdered food such as wheat flour, coffee powder and milk powder was measured and analyzed. In the uniform range of bulk density of material, the real parts of permittivity of the food samples increased with the increase of moisture content, bulk density and temperature of the samples. The propagation properties such as attenuation and phase shift increased linearly as the moisture density of the food samples increased. As a measuring frequency of the moisture content, the X-band was recommended.
